RELATED APPLICATIONS

The present application claims the benefit of U.S. Provisional PatentApplication No. 60/909,212, filed on Mar. 30, 2007, and is incorporatedby reference and made a part hereof.

TECHNICAL FIELD

The present invention generally relates to a personal device used inathletic activity and, more particularly, to a device worn by an athletesuch as a runner wherein the device has functionality triggered by RFIDsources.

BACKGROUND OF THE INVENTION

Running is a popular form of physical fitness. In conjunction withgeneral running activity, runners often participate in race events suchas marathons, 5 ks, 10 ks or other races of varying distances. To judgefitness levels and progress, runners often will record the time it takesto finish a race. Runners may often utilize a stop watch incorporatedinto a traditional wrist watch that records elapsed time. The watch mayhave the capability to store split times as a runner progresses along arace course by manually pressing a lap/split button on the watch.Technological advances have provided more sophisticated time keeping,particularly for race events wherein hundreds and even thousands ofrunners participate in the event. For example, one system provides anautomatic timing system utilizing radio frequency identification (RFID)technology. In the system, mats having antennas incorporated therein areplaced at the start, finish and other timing locations along a racecourse. A runner wears a miniature transponder that interacts with themats as the runner progresses along the race course. As the runner runsthe event, time is automatically kept via interaction between thetransponder and the mats. Time data is transmitted to a central locationwherein race officials can monitor the progress of the race and thetimes of every participant.

These types of race event systems are typically administered by the raceorganizer. Accordingly, the time data is also controlled by the raceorganizer. Using the official race event transponders associated withthe system, a runner has limited control over the timing data and doesnot have easy access to make further use of the timing data. Inaddition, the device usually must be returned to the race organizer. Incertain instances where a transponder can be purchased separately, thetransponder generally does not have further utility accept for otherraces utilizing the same type of timing system. Accordingly, whilecertain race event devices provide a number of advantageous features,they nevertheless have certain limitations. The present invention seeksto overcome certain of these limitations and other drawbacks of theprior art, and to provide new features not heretofore available.

The band 36 can be made from a resilient, elastic type materialin the form of a solid ring wherein the band 38 can easily stretch overa hand and fit upon the wrist in a generally snug fashion. Inalternative forms, the attachment member 32 can include different typesof attachment structures such as buckles, snaps, hook and loop fastenersor other types of fasteners if desired. The attachment member 32 couldinclude a break in the structure allowing the member 32 to fit over thewrist via the break. The attachment member 32 can also include otherdesirable indicia thereon as well as a variety of different colors. Theattachment member 32 is further structured and dimensioned to house andsupport the chip system 34.

As further shown in FIG. 2, the chip system 34 is capable of receivingand transmitting signals and data and generally includes a transponder38, a microprocessor 40, and a display 42. It is understood that thechip system components are operably connected to provide the functionsand interactions described herein.

In one exemplary form of the invention, the transponder 38 is an activeor passive RFID chip or tag 38. The RFID tag 38 is capable of receivingan initial signal such as magnetic signal from the mat 14 andtransmitting a reply in response to the initial signal. Themicroprocessor 40 can take many different forms and is generally a unitthat processes or controls steps, actions and commands associated withthe interaction between the device 10 and the timing system 12. Themicroprocessor 40 specifically includes a simple chronograph 44 foraccurate recording of time. Specific functionality associated with themicroprocessor 40 will be described in greater detail below whendiscussing the operation of the device 10 in use with the timing system12.

The microprocessor 40 also includes memory 46. The memory 46 can be asmall amount of flash memory such as EEPROM, and around 1 k in size,although the size of the memory can vary. The microprocessor 40 furtherincludes a power supply 48 such as a battery 48. The battery 48 can takevarious forms and in an exemplary embodiment, the battery 48 could be apaper battery or similar to a battery used in hearing aid applications.Finally, the display 42 may be a simple display such as a flexible,plastic LED or LCD. The display 42 can be flexible to adhere to thecontour of a wrist. The display 42 is mounted in a location wherein arunner can easily view the display 42. In addition, the chip system 34may include a user input module 45 wherein the athlete can inputinformation as desired. As described in greater detail below, the chipsystem 34 may also have a communication element 49 for wirelesscommunication. It is understood that the various components of the chipsystem 34 may be contained within a small housing that is supported bythe attachment member 32. It is further understood that the chip system34 can be capable of wireless transmission and overall wirelesscommunication with other types of devices, as well as be equipped withdata transmission ports if desired.

Operation of the personal athletic device 10 will now be described usinga marathon event as an example. As described above, the mats 14 arepositioned along the designated race course 22 (FIG. 3). A mat 14 isplaced at the start 24 of the course 22 as well as at the end of thecourse defining the finish line 26. In addition, a plurality of othermats 14 are positioned at intermediate locations along the race course22 such as at each mile marker, e.g. from mile marker no. 1 through milemarker no. 26. It is understood that the mats 14, equipped with theappropriate antennas etc., will generate a magnetic field F (FIG. 1)from the mat 14.

A runner participating in the marathon event wears the device 10 on thewrist wherein the device 10 may simply be considered a bracelet. As therunner starts the race, the mat 14 at the starting line 24, via thegenerated magnetic field F, triggers the RFID tag 38 which in turnstarts the chronograph 44 of the microprocessor 40. The elapsed racetime is also displayed on the display 42. Each subsequent mat 14 alongthe race course similarly triggers the RFID tag 38 and displays a milesplit time on the display 42. The chip system 34 is designed to displaythe split time for several seconds on the display 42 and then change thedisplay 42 to continue displaying the elapsed race time. The device 10may also have a vibration signal, audible signal or other type of signalto indicate to the runner to view the display 42 to see the split time.It is further understood that when the RFID tag 38 is triggered at themile markers, the split times are also saved in the memory 46. At thefinish 26, the mat 14 at the finish line triggers the RFID tag 38 torecord and display the final race time and stop the chronograph 44. Intypical configurations, a runner uses a watch and presses a lap/splitbutton on the watch upon reaching each mile marker along the racecourse. The personal athletic device 10 may be considered a simplerunners chronograph wherein the lap/split button is replaced by the RFIDprompt at the mile markers and the interaction between the device 10 andthe timing system 12. Split times and finish time can then beautomatically recorded personally by each runner eliminating the needfor manual steps taken by the runner. In addition, this information isimmediately displayed to the runner rather than only being saved by thecontroller 16 of the timing system 12 administered by the raceorganizer. Until now, such data was not immediately available to therunner by being shown on the display 42.

The personal athletic device 10 may also have enhanced timingcapabilities. For example, a runner may design a race plan havingdesired target split times. Prior to the race, the runner uploads thetarget split times and stores the times in the memory 46 of the device10. The uploading can take place from various locations such as apersonal computer, a kiosk that may be affiliated with the raceorganizer or other interested entity, and further be done either througha data port connection or wireless transmission. With respect to aparticular marathon course, the kiosk could calculate corrected milesplit times if necessary and place the times on the device 10 in thememory 46. During the race, at each mile marker, the display 42 showsthe actual split time as described above as well as the target splittime pre-entered into the device 10 for comparison by the runner. Themicroprocessor 40 may have additional communication capabilities toindicate to the runner whether the runner is on pace, ahead of pace, orbehind pace as preset by the runner.

In another exemplary embodiment, the personal athletic device 10 cantake more a more simplified form in functionality and merely display afinish time of a race event. Accordingly, the personal athletic device10 is activated when the runner passes the starting line and thechronograph 44 keeps time as the runner progresses along the course 22.Upon crossing the finish line 26, the final time is displayed on thedisplay 34 such as shown in FIG. 5. In this embodiment, the display 42is preferably a bi-stable display 42A wherein the finish time isperpetually displayed on the display 42. As the display 42 is abi-stable display, no power is required for the display 42 tocontinually display the finish time. As such, the personal athleticdevice 10 can be used as a souvenir or keepsake from the race event tobe placed on a shelf or mantle.

As discussed, the personal athletic device 10 can have wirelesstransmission capabilities. The device 10 could transmit the timinginformation for the runner to another computer which could transmit theinformation to another location such as a website having additionalfunctional capabilities. For example, the website could displayadditional race times for comparison or race times for runners in aparticular group. The website could be a website affiliated with therace organizer or a separate website associated with the runner. It isalso understood that in another exemplary embodiment of the invention,the device 10 could not include the display 42. In this configuration,the race data including split times can be downloaded to anothercomputer such as at a kiosk for additional transmission such as to awebsite.

It is understood that the personal athletic device 10 is programmed witha unique RFID serial number. This unique number can be associated withthe name and personal information of an individual. Accordingly, withappropriate cooperation with race organizers, the personal athleticdevice 10 could be used to enter race events such as at a kiosk or othercentral location. As all of the pertinent information is contained inthe device 10, registration can be streamlined and more efficient.Payment capabilities such as using credit card or other informationcould also be incorporated into the device 10 to further enhanceregistration capabilities.

It is understood that wearing the personal athletic device 10 on thewrist is one exemplary form of the invention. The device 10 can also beworn on other locations such as the arm, on apparel, on glasses having adisplay, as well as on shoes if desired. The device 10 could also beequipped with an audio component wherein an athlete can hear timeinformation via earphones.

It is also understood that the personal athletic device 10 and itsfunctionality could be incorporated into a full featured watch havingtraditional watch functions, a phone, a digital music player, a heartrate monitor, electronic devices worn on or in soles of shoes, or otherelectronic devices. The device 10 could also be equipped with enhancedcommunication capabilities to communicate with such other electronicdevices as schematically indicated in FIG. 1. With respect to a digitalmusic player configuration, the functionality of the present inventioncan specifically be incorporated into an IPOD® brand digital musicplayer available from Apple, Inc. of Cupertino, Calif. In such aconfiguration, there can be ongoing audio communication to the runnerincluding specific timing related communications based on the variouscheckpoints or mile markers reached during a race event. Communicationsto the device 10 could also take various forms including custom coachingor motivational messages. The RFID triggers could also incorporateglobal positioning functions including pre-entering location informationabout a race course. A GPS signal could then trigger the device 10 toprovide useful information to the runner.

While a specific example has been described herein relating to amarathon event, it is understood that the personal athletic device 10could be used in other timed events. For example, bikers and swimmerscould also use the device as well as athletes participating intriathlons.

The personal athletic device 10 of the present invention possessesenhanced functionality over prior art systems. The device 10 can bedesigned to be reused at multiple race events. The memory can be clearedand the chronograph can be reset for another race. The memory could alsobe sized to maintain race data for multiple events. Alternatively, thedevice 10 can be designed for a one-time use, such as the embodimentdescribed above having the bi-stable display. Furthermore, thecomponents of the device 10 can be selected having the functionalitydescribed above but wherein the device 10 is considered to be for aone-time use and disposable. Using the device 10 of the presentinvention is more desirable than the traditional shoe-mountedtransponder as the device 10 provides a display as well as instantaccess to the timing data generated with the timing system 12 forfurther use and review by the runner.

Finally, the personal athletic device 10 can be utilized in displayingmessages at locations unrelated to timing events. For example, a retailestablishment could include mats 14 or other appropriate signalgenerating device at its location. An individual wearing the device 10and entering the location could be randomly selected to win a rewardsuch as merchandise or other reward. A message could be displayed on thedisplay 42 indicating “winner.” The device 10 could also be used forgaming such as scavenger hunts to log that a person was near adesignated marker.
